Hello
We now have an FAQ to explain how the stiffness is calculated for the soil layers:
http://www.graitec.com/en/FAQ_view.asp?FAQID=1103
To select support results you need to go to "Results settings" from the Analyze menu (or Results toolbar). Select the type of result from the drop down list on the left (deflections, forces, stresses, torsors) and select "support" or "planar support" from the available options in the left hand window and tick the required degree of freedom (eg "FZ")
